无法确定 AWS 的事件类型 Lambda 无服务器 function

Question

我有一个非常简单的处理程序，我用它来熟悉无服务器 lambda 函数。

const example: APIGatewayProxyHandler = async event => {
  console.log(JSON.stringify(event, null, 2));
  return {
    statusCode: 200,
    body: JSON.stringify({
      message: 'Success',
    }),
  };
};

这是我的 serverless.yml 文件：

service: lambda-example
frameworkVersion: '2'

provider:
  name: aws
  runtime: nodejs12.x

plugins:
  - serverless-offline

functions:
  example:
    handler: lib/handler.example
    events:
      - http:
          path: example
          method: get
          integration: lambda

当我点击 API 时，它工作得很好......

{
  statusCode: 200,
  body: "{"message":"Success"}"
}

我正在使用这个 URL 来触发事件http://localhost:3000/dev/example?url=https://google.com/并且当端点被击中时我正在控制台记录事件本身......

{
  "body": {},
  "method": "GET",
  "principalId": "offlineContext_authorizer_principalId",
  "stage": "dev",
  "cognitoPoolClaims": {
    "sub": ""
  },
  "enhancedAuthContext": {
    "principalId": "offlineContext_authorizer_principalId"
  },
  "headers": {
    "Host": "localhost:3000",
    "Connection": "keep-alive",
    "Cache-Control": "max-age=0",

    "Sec-Fetch-Site": "none",
    "Sec-Fetch-Mode": "navigate",

    "Sec-Fetch-Dest": "document",
    "Accept-Encoding": "gzip, deflate, br",
    "Accept-Language": "en-US,en;q=0.9,la;q=0.8"
  },
  "query": {
    "url": "https://google.com/"
  },
  "path": {},
  "identity": {
    "accountId": "offlineContext_accountId",
    "apiKey": "offlineContext_apiKey",
    "apiKeyId": "offlineContext_apiKeyId",
    "caller": "offlineContext_caller",
    "cognitoAuthenticationProvider": "offlineContext_cognitoAuthenticationProvider",
    "cognitoAuthenticationType": "offlineContext_cognitoAuthenticationType",
    "sourceIp": "127.0.0.1",
    "user": "offlineContext_user",
    "userAgent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.111 Safari/537.36",
    "userArn": "offlineContext_userArn"
  },
  "stageVariables": {},
  "requestPath": "/example"
}

我有兴趣访问这个 object 的“查询”属性，但是当我尝试时 TypeScript 对我很生气......

console.log(event.query);

===

Property 'query' does not exist on type 'APIGatewayProxyEvent'.

查询属性非常清楚地存在于事件 object 中，如我的控制台日志中所示，因此我假设我错误地输入了这个 function，但我似乎找不到正确的类型。 我在这里做错了什么？

Answer 1

原来问题是

integration: lambda

除了我的 serverless.yml 文件。 当我删除此行时， APIGatewayProxyHandler接口按预期工作。
